It's to gauge the distance e between you & car in front so you have time to stop. You see the car pass a landmark & count 3. If you reach it before 3, you are too close.
keep a three second distance between you and the car in front of you. about 10 to 15 feet
The 3 second rule (sometimes it's a 2 second rule) refers to the spacing a vehicle should maintain when following another vehicle, regardless of speed. The theory is that the faster the vehicles are traveling, the greater the margin of safety (spacing or distance) between the vehicles will be.
Yes, using either the 2-second rule or the 3-second rule means that as your driving speed increases, you leave more distance between you and the car ahead of you.
One second.
When following a vehicle in front of you.
Always and every time you're behind the wheel. If every driver followed this rule, auto accidents would fall dramatically.
The four second rule is very simple, while following another vehicle when he passes a certain line or passes under a bridge you simply starting of the seconds and you should be at the four second mark or higher.
to be able to understand/estimate the distance it would need to stop safely in case of an emergency, hence the 3 second gap rule for city driving and 5 second gap rule for highway driving, they estimate that to be about the distance you would need to have at the posted speed limit
You should keep at least a three second distance to the car ahead.
The 3 seconds file on driving refers to what?
no
After a shot.
The 3 second rule refers to dropping a piece of food on the floor and if you pick it up within three seconds, it is still safe to eat.
